Popular Science Monthly/Volume 45/September 1894/Obituary Notes


The death is announced at Geneva, Switzerland, of the eminent chemist, J. C. de Marignac, formerly professor in the University of Geneva. He retired from his professorship in 1878, but continued his studies in a laboratory, which he fitted up at home, till the end of his life. He was well known for his researches on ozone and on chlorine, silver, potassium, sulphuric acid, and other substances in the domain of mineral chemistry. He was a correspondent of the Institute of France, and received the gold medal of the Royal Society in 1886. He was modest to excess and led a retired life of labor, the fruits of which made his name known throughout the world.

The death is announced of Prof. Adolph Leipner, Professor of Botany in University College, Bristol, England. He had been honorary secretary from its beginning in 1862, and was at the time of his death President of the Bristol Naturalists' Society.

Prof. August Kundt, the eminent physicist, died May 21st at his country place near Lubeck, fifty-four years of age. He was born at Schwerin in 1839 and was graduated from the University of Berlin in 1864, presenting as his thesis an investigation on the depolarization of light. He became a privatdocent in the University of Berlin in 1867, and was afterward a professor in the Polytechnic Institution at Zurich, at Würzburg, in the University of Strasburg, in the organization of which he had an important part, and in the Berlin Physical Institute, where he was also director. His first investigations were in acoustics and were gradually extended to embrace a large range of subjects. Perhaps the most important of them were in optics and magneto-optics.

M. A. Derbès, one of the pioneers in the study of the life history of the algæ, has recently died in Marseilles, France. In conjunction with M. Solier he was the author of a work on Zoöspores of the Algæ and the Antharides of the Cryptogams, published in 1847, which was rich with new facts and formed the basis of all later observations on the same subject.
